Four years at Cathedral is only the beginning. Cathedral connects you with a long and storied line of graduates who number among their ranks a Nobel Prize winner, Pulitzer Prize winner, the mayor of Indianapolis, the first African-American female federal judge in the state of Indiana, Olympic athletes, professional athletes, and business, community, and civic leaders. Whether raising a family or raising millions of dollars in a capital campaign, Cathedral graduates display the unique character created by Holy Cross values.

Cathedral has one of the largest and most active alumni networks of any high school in the state—more than 16,000 members strong. Now, with alumni chapters in Florida, Colorado, California, Illinois our alumni keep in touch with classmates and our school, renewing that Cathedral connection throughout their lives.

Be “Always Irish.” Connect, volunteer, communicate, and donate and benefit from the lifelong connection of being a Cathedral High School graduate.
